All you need to do is btrfs dev delete for the two devices you want removed. What I don't know off hand is if it's OK to delete both devices right away at the same time. So unless you want to find out (i.e. take a risk) I suggest either waiting for someone else to reply whether this should work, or I'd delete them separately: wait for the first delete to succeed before starting the next one. > btrfs replaces somthing ? > Not necessary because you've already added two devices. So you can just delete the two you want removed. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
